Envy

Based on a couple other UIs that I've seen and adapted them to fit my needs.

READ THE README!

Also, check your keybindings for things like:

Show/Hide Minimap
GoGoMount
Bartender
etc.

EDIT 10-31:
Yes. I found out that I hadn't placed the class bar or the pet action bar. I suppose that's what I get for only testing the UI on a priest and a shaman. This will be resolved in the next release (within the next couple days, I hope).
